Yeh when starting out first box wants be value for money and possibly expandable so can grow with it a bit and not need complete change for a while.
Used branded nice but tends be hard find something worth having unless luck on your side .
Masterforce Husky or the HF boxes when at best offer prices are quite good buys.
HF 72" at $999 is pretty good buy, not so keen on the 56" drawer layout but 22" depth is nice plus have side expansion cabinets cheap, Masterforce has best range of sizes, quality construction/latching and colours plus expansion cabinets.
Would be good consider all options including a local look at used and see where it takes you. be smart as wise first box can last, grow or turn into a home box or if buy used you likely sell on with no or little loss .
